1 / 53 “Intraocular lens with power factor and structure to improve peripheral vision” FIELD OF THE INVENTION

[0001] The embodiments of the present invention relate to apparatus, systems and methods for manufacturing intraocular lenses that provide corrective vision with improvements to peripheral vision as well. BACKGROUND

[0002] The embodiments of the present invention relate to vision treatment techniques and, in particular, to ophthalmic lenses, such as intraocular lenses (IOLs), including, for example, phakic intraocular lenses and piggyback intraocular lenses (i.e., intraocular lenses implanted in an eye that already has an intraocular lens).

[0003] Intraocular lenses (IOLs) can be used to restore visual performance after a cataract or other ophthalmic procedure in which the natural crystalline lens is replaced or supplemented by the implantation of an intraocular lens. When such a procedure alters the optics of the eye, one goal is usually to improve central vision. Recent studies have found that when a monofocal intraocular lens is implanted, peripheral aberrations are altered, and that these aberrations differ significantly from those of normal phakic eyes. The predominant change is observed in relation to peripheral astigmatism, which is the main peripheral aberration in the natural eye, followed by sphere and then higher-order aberrations. Such changes can have an impact on overall functional vision, including the ability to drive, fall risk, postural stability, and / or detection ability.

[0004] There are also certain retinal conditions that reduce central vision, such as age-related macular degeneration (AMD) or a central scotoma. Other diseases can affect central vision, even at a very young age, such as Stargardt disease, the disease Petition 870250103047, dated 11 / 11 / 2025, p. 7 / 75 2 / 53 of Best and reverse retinitis pigmentosa. The visual outcome for patients suffering from these conditions can be improved by enhancing peripheral vision.

[0005] Peripheral vision can also be impaired by glaucoma. Glaucoma affects 2% of the population over 40 years of age. Patients with glaucoma gradually lose peripheral vision as a result of damage to the optic nerve. Central vision may degrade in very advanced stages of the disease. Significant disabilities in daily life can occur due to glaucoma, including problems with walking, balance, risk of falls, and driving. Patients suffering from glaucoma may benefit from intraocular lenses that improve both central and peripheral vision.

[0006] In light of the above, lenses that improve peripheral vision are necessary. BRIEF SUMMARY

[0007] The present invention solves the above problems by providing lenses with power format factor and diopter marking power ranges that correspond to lenses with optimized on-axis visual acuity and contrast sensitivity and with a blur parameter less than 1.8 diopters (D), which therefore improve peripheral vision. Furthermore, lenses are provided with format factors and diopter marking powers that fall within sub-ranges corresponding to an optimal peripheral vision lens that minimizes off-axis astigmatism to 20 degrees of eccentricity while maximizing on-axis visual acuity and contrast sensitivity, and the optimization parameters are described herein.

[0008] In particular, a first embodiment of an intraocular lens comprises a lens body, wherein the lens body comprises: a refractive index between 1.40 and 1.50 inclusive, a diopter marking power between 17 D and 23 D inclusive, and a factor Petition 870250103047, dated 11 / 11 / 2025, page 8 / 75 3 / 53 of power format that is less than or equal to -1.0 and greater than or equal to -2.5. Advantageously, providing an intraocular lens according to the marking power range and the power format factor range of the first modality allows for the correction of peripheral astigmatism according to a blur parameter less than 1.8 D, while optimizing visual acuity on the axis. Within these ranges, the power format factor is stable, meaning that structural features can be selected to produce lenses that are predictably capable of producing the effect of reducing off-axis astigmatism to 20 degrees of eccentricity, while optimizing visual acuity on the axis. These ranges are critically important for enabling predictable correction of peripheral astigmatism for patients with a dioptric power requirement less than a transition point power.The transition point power is the marking power that corresponds to the format factor of a plano-convex lens, which is -1.

[0009] The lens body may comprise a central thickness between 0.62 mm and 1.0 mm. The intraocular lens may additionally comprise an anterior haptic connected to the lens body, and the lens may comprise an arc height between 0.34 mm and 0.65 mm. The lens may comprise a first surface with an anterior surface curvature greater than -0.077 mm-1 and less than 0.00 mm-1 and a second surface with a posterior surface curvature greater than 0.355 mm-1 and less than -0.130 mm-1. Advantageously, selecting any of these parameters to be within their respective ranges increases the adaptability of the lenses, allowing the lenses to be implanted with industrially available inserters. These ranges for each parameter also prevent the lenses from being excessively closed and thus reduce discomfort when inserted into a patient.The selection of these parameters also allows the lenses to have a specific format factor. Petition 870250103047, dated 11 / 11 / 2025, page 9 / 75 4 / 53 power that is even more stable within the ranges of the invention, to further assist the lenses' ability to predictably improve peripheral vision.

[0010] The lens may comprise a diopter marking power that is between 18 D and 22 D inclusive. The power format factor may be less than or equal to -1.1 and greater than or equal to -2.0. Advantageously, these marking power and power format factor ranges result in a lens that is optimized so that the lens minimizes off-axis astigmatism while maximizing on-axis visual acuity for lenses with a marking power less than the transition point power. Within these ranges, the lens's power format factor is particularly stable, which is critically important for enabling greater predictability of the lens's structural characteristics that result in optimization. The lens may comprise a center thickness that is between 0.70 mm and 0.90 mm. An anterior haptic may be attached to the lens body, and the lens may comprise an arc height that is between 0.40 mm and 0.60 mm.The lens may comprise a first surface with an anterior surface curvature greater than -0.071 mm-1 and less than -0.00 mm-1 and a posterior surface curvature greater than -0.355 mm-1 and less than -0.134 mm-1. Advantageously, selecting any of these parameters to be within their respective ranges increases the adaptability of the lenses, allowing the lenses to be implanted with industrially available inserters. These ranges for each parameter also prevent the lenses from being excessively closed and thus reduce discomfort when inserted into a patient. The respective selection of these parameters additionally allows the lenses to have a power format factor that is even more stable within the optimization ranges, to further assist in the ability of the lenses to predictably minimize peripheral vision while maximizing [missing information].

Advantageously, the provision of an intraocular lens according to the marking power range and the power format factor range of the second type allows for the correction of peripheral astigmatism according to a blur parameter less than 1.8 D, while optimizing visual acuity on the axis.

Advantageously, selecting any of these parameters to be within their respective ranges increases the adaptability of the lenses, allowing the lenses to be implanted with industrially available inserters. These ranges for each parameter also prevent the lenses from being excessively closed and thus reduce discomfort when inserted into a patient.The selection of these parameters further allows the lenses to have a power format factor that is even more stable within the ranges of the invention, to further assist the lenses' ability to predictably improve peripheral vision.

The concave surface may comprise a radius of curvature on the front of the concave surface that is greater than a radius of curvature on the back of the convex surface.

[0020] The power format factor can be calculated according to Power^^^i-Power^ nost with the formula----------------p—, where Powerant is the power of Potênciaant+Potênciapos is the anterior surface power, and Potênciapos is the posterior surface power of the lens body.

[0048] This invention considers multiple types of ophthalmic lenses used to correct vision and presents reliable solutions to problems involved when an intraocular lens must be implanted in a patient and provides reliable positioning for structural features of intraocular lenses of different marking powers.

[0049] The embodiments of this invention incorporate the common meaning of the terms of the art in the field of intraocular lenses. For example, as shown in Figure 2, this invention relates to haptics 320 attached to a lens body that are fitted to hold the intraocular lens 300 in place in a patient's eye. The haptics 320 establish an anterior haptic plane 325 which is a useful reference point for comparative purposes of different lenses. An anterior haptic plane 325 is defined by a plane that is normal to the optical axis and extends through the most anterior surface of the uncompressed intraocular lens haptics 320. As shown in Figure 2, an arc height 350 of an intraocular lens is the distance between the anterior haptic plane 325 and a plane normal to the optical axis containing an anterior surface 330 of the intraocular lens body, calculated as defined in ISO 11979-1.Figure 2 also shows a measurement of a central thickness 310, which is the difference between the sagittal thickness and the arc height, as defined by ISO 11979-1. The intraocular lens body in Figure 2 has an anterior surface 330, a posterior surface 340, a frontal principal plane determined, at least in part, by the optical effects of the anterior surface of the intraocular lens 300, and a posterior principal plane determined, at least in part, by the optical effects of the posterior surface of the intraocular lens 300. This invention calculates the best possible structure for a given marking power. Petition 870250103047, dated 11 / 11 / 2025, p. 22 / 75 17 / 53 measured in diopters. As used herein, marking power refers to dioptric power as defined in ISO 11979-1, which can be calculated using ray tracing techniques. The central thickness 310, anterior surface curvature, and posterior surface curvature are used according to standards in the intraocular lens technique. Standard materials for forming intraocular lenses are within the scope of this invention. In various implementations, the optics may comprise materials such as acrylic, silicone, polymethyl methacrylate (PMMA), styrene-ethylene-butylene-styrene (C-FLEX) block copolymers or other styrene-based copolymers, polyvinyl alcohol (PVA), polystyrenes, polyurethanes, hydrogels, etc.

[0050] This invention uses power format factor values ​​for intraocular lenses (IOLs) to identify structural features of intraocular lenses necessary to achieve different marking powers measured in diopters (D) that are suitable after implantation in patients. By managing and manipulating at least the structural features disclosed herein and shown in Figure 2 and equations 1 to 10 below, the intraocular lenses of this invention perform extremely well in treating eye diseases and maintaining focus and clarity for both foveal and peripheral vision for a patient receiving an implanted intraocular lens.

[0051] As an initial introduction, this invention uses at least two different intraocular lens structures that are configured as peripheral vision correction intraocular lenses as non-limiting examples that show the characteristics and benefits of the work disclosed herein. Figure 2 illustrates a lens in which the concave surface faces the object to be photographed and / or the light source of the image. An intraocular lens may have convex surfaces on the anterior and posterior sides of the intraocular lens. Plano-convex intraocular lenses Petition 870250103047, dated 11 / 11 / 2025, p. 23 / 75 18 / 53 have an anterior surface that is flat or substantially flat and a convex posterior surface.

[0052] The power format factor varies for different lens types, but it can also be constant for a lens with a flat surface. For example, a constant power format factor is equal to minus one (-1) for a plano-convex lens. In non-limiting embodiments, intraocular lenses with power format factors that are less than or equal to minus one (-1) are provided, and intraocular lenses with power format factors that are greater than or equal to minus one (-1) are also provided. An intraocular lens with a power format factor greater than or equal to minus one may have a lens body that is formed differently from the lens body of an intraocular lens with a power format factor less than or equal to minus one.Without limiting this invention to any specific power format factors or marker powers, the lenses of this invention may have a marker power range of about 17D to 35D to illustrate various embodiments. At a constant power format factor of a plano-convex lens (e.g., minus 1), the lens shape transitions from that of a lens with a power format factor less than or equal to minus one to that of a lens with a power format factor greater than or equal to minus one. At lower marker power ranges, including but not limited to a range of 7D to 17D, the anterior and posterior surfaces of the intraocular lens do not necessarily exhibit power responses that would be expected from simple surfaces with consistent curvature across the anterior and posterior surfaces.Instead, the anterior and posterior surfaces of the intraocular lens may effectively include complex surfaces that vary across their respective surfaces. The variance between the surfaces may be in terms of variations in surface curvature (i.e., exhibiting structures of...). Petition 870250103047, dated 11 / 11 / 2025, page 24 / 75 19 / 53 toroidal surface or Zernike surfaces) and may require further investigation to ensure that a desired and reliable response is provided after intraocular lens implantation in a patient.

[0053] The power format factor of an intraocular lens is calculated according to the formula: Power before - Power after Powerant + Powerpost (Equation 1), where Powerant is the anterior surface power, and Powerpost is the posterior surface power of the lens body.

[0054] The previous surface power is calculated according to: Power^ =n'0L~n^“O(Eq. 2)Rant

[0055] The power of the posterior surface is calculated according to: n_L^ _.nmeio -nIOL Power = ------------ (Eq. 3) ^ Rpost Let Rant be the anterior radius of curvature, and Rpost is the posterior radius of curvature of the lens body. A first surface of an intraocular lens defines the anterior radius of curvature Rant, and a second surface defines the posterior radius of curvature Rpost. n-medium is the refractive index of the intraocular lens, while n-medium is the refractive index of the medium in which the intraocular lens is implanted. For power in diopters, radii must be given in millimeters.

[0056] The radius format factor for an intraocular lens is calculated according to the formula (Rp°st-R αη) (Eq.4). Rpost+Rant, where the ray format factor uses the general marking radius of curvature for each lens, the power format factor can be calculated by ray tracing techniques applied to the intraocular lens. In some non-limiting modalities, ray tracing techniques may include the use of a specific aperture size. Ray tracing techniques may also involve using a specific aperture size, a better focus position, and spherical aberration effects in the Petition 870250103047, dated 11 / 11 / 2025, page 25 / 75 20 / 53 power format factor. The power format factor and the radius format factor may be equal for ideally simple surfaces of known curvature, but the values ​​are not always the same, indicating more complicated surface curvatures.

[0057] The lensmaker's formula illustrates how the focal length of an intraocular lens is affected by the radius of curvature of the anterior and posterior surfaces, where F is the focal length, ni_io is the refractive index of the lens, Ri is the radius of curvature of the first surface, and R2 is the radius of curvature of the second surface: 1 = (nI0L - 1)(-1 - 1-) (Equation 5) r «1 «2

[0058] Prior technique efforts, such as the 100 intraocular lens shown in Figure 1, focused on the lensmaker's equation to adjust radius values ​​and focal lengths for intraocular lenses without in-depth analysis of the variable power responses that anterior and posterior surfaces may exhibit after implantation.

[0059] The measurements given throughout this application are discussed in relation to the Liou and Brennan ocular model (Liou HL, Brennan NA. Anatomically accurate, finite model eye for optical modeling. J Opt Soc Am A Opt Image Sci Vis. August 1997;14(8):1684 to 1695. doi: 10.1364 / josaa.14.001684. PMID: 9248060). For the lenses of this invention, the arc height ranges are chosen between 0.34 mm and 0.65 mm. The lenses may comprise arc heights in the range of 0.40 mm to 0.60 mm or 0.50 mm to 0.55 mm. The arc height may be 0.65 mm. The center thickness is chosen in the range of 0.62 mm to 1.0007 mm. The center thickness can vary from 0.70 mm to 0.90 mm or from 0.80 mm to 0.85 mm. The format factor can range from -4 to 0. These parameter ranges are selected to provide lenses that can be implanted with industrially available inserters, as well as to avoid producing lenses that are excessively closed, thus avoiding the production of lenses that are too closed. Petition 870250103047, dated 11 / 11 / 2025, p. 26 / 75 21 / 53 mode, to reduce discomfort in a patient. For these reasons, lenses with a posterior radius smaller than -4 mm are also excluded from this invention. In this invention, the length of the eye is fixed by the paraxial focus of an equivalent ZCB00 lens (Tecnis® monofocal) with a 2D power below the marking power of the intraocular lens (i.e., an intraocular lens with a marking power of 22D uses the length of the eye corresponding to a ZCB00 20D lens).

[0060] An implanted intraocular lens can be classified as a peripheral vision correcting lens if, for the implanted intraocular lens, the off-axis astigmatism measured at 20 degrees of eccentricity from the optical axis through the iris is less than or equal to a threshold value of 1.8 D. Eccentricity refers to the angular distance from the center of the visual field, such as the fovea centralis. Off-axis astigmatism at 20 degrees can be calculated according to a peripheral blur parameter of an intraocular lens, as measured at that angle. For example, for an intraocular lens with a 20 D marking power that corrects peripheral vision, the peripheral astigmatism might be 1.3 D or 1.7 D at 20 degrees of eccentricity.

[0061] The vectors Jo and J45, as well as the sphere, cylinder, and blur parameters, can be calculated. These values ​​are calculated according to the following equations, in which C(i, j) are corresponding Zernike coefficients in pm, er is the pupil radius in mm. For these formulas, a negative sign convention is used for the cylinder definition, and the retinal curvature is defined according to Atchinson et al. (Optical models for human myopic eyes, 2006). 2V6 · C(2, 2) ^2 (Eq. 6) 2^6·E(2, -2) ^2 (Eq. 7) Sphere = - 4^2, 0)(Eq. 8) Petition 870250103047, dated 11 / 11 / 2025, page 27 / 75 22 / 53 Cylinder = -2 · V / 02+ J452 (Eq. 9) Blur parameter = jSphere2 + Cylinder2 (Eq. 10)

[0062] With reference to Figures 4 and 5, this invention provides ranges that are of critical importance for lenses with marking powers that correct peripheral vision according to the blur parameter condition, have an absolute value below 1.8 D for peripheral cylinder at 20 degrees of eccentricity, and optimize on-axis visual acuity and contrast sensitivity. On-axis visual acuity and contrast sensitivity are optimized for selected values ​​of arc height, center thickness, and format factor within the ranges discussed in the present invention. For the selected values, on-axis visual acuity and contrast sensitivity are optimized by adjusting the anterior and / or posterior aspheric parameters to produce a lens with on-axis performance that is as close as possible to diffraction-limited performance for a 5.65 mm on-axis entrance pupil in green light (550 nm).Graph 400 in Figure 4 shows peripheral vision lenses with a refractive index of 1.471 that correct peripheral vision according to the blur parameter condition, have an absolute value below 1.8 D for the peripheral cylinder at 20 degrees of eccentricity, and optimize visual acuity on the axis and contrast sensitivity, while graph 500 in Figure 5 shows peripheral vision lenses with a refractive index of 1.55 that correct peripheral vision according to the blur parameter condition, have an absolute value below 1.8 D for the peripheral cylinder at 20 degrees of eccentricity, and optimize visual acuity on the axis. Both Figure 4 and Figure 5 show, respectively, plots of the format factor against the marking power for lenses that satisfy the conditions. In both plots, the lenses are restricted by having an arc height between 0.34 mm and 0.65 mm and a center thickness in the range of 0.62 mm to 1.0007 mm. Petition 870250103047, dated 11 / 11 / 2025, page 28 / 75 23 / 53

[0063] With reference to graphs 600 and 700 of Figures 6 and 7, respectively, this invention also provides sub-ranges corresponding to optimal marking powers and power format factors that are of critical importance for a peripheral vision lens that maximizes off-axis astigmatism reduction at 20 degrees of eccentricity while maximizing on-axis visual acuity and contrast sensitivity. Figure 6 shows the optimal region for a refractive index of 1.471 as shaded regions 610 and 620. Figure 7 shows the optimal region for a refractive index of 1.55 as shaded regions 710 and 720. In both graphs, the lenses are constrained by having an arc height between 0.34 mm and 0.65 mm and a center thickness in the range of 0.62 mm to 1.0007 mm.

[0064] To calculate these sub-bands corresponding to regions 610, For 620, 710, and 720, an optimization of a modulation transfer function (MTF) was performed. Contrast sensitivity is known to be proportional to the Modulation Transfer Function (MTF); thus, sufficient on-axis visual acuity and / or contrast sensitivity can be achieved through MTF optimization. Optimization can be performed at one or more spatial frequencies or using a figure of merit proportional to the MTF levels at one or more spatial frequencies. In a non-limiting example, sufficient contrast sensitivity is achieved if the MTF is at least 0.7 for a 5 mm pupil in green light at a spatial frequency of 50 cycles / mm, as measured in eye model #2 according to ISO 11979-2 2014.The following parameters and their associated weighting for MTF optimization are as follows: a lens that is diffraction-limited on-axis for a large entrance pupil of 5.65 mm (weight = 1); reduce each of off-axis astigmatism and off-axis defocus by 20 degrees for an entrance pupil of 4 mm (weight = 0.01 each); increase. Petition 870250103047, dated 11 / 11 / 2025, p. 29 / 75 24 / 53 MTF values ​​are 20 degrees off-axis for each of the sagittal and tangential foci at a spatial frequency of 25 cycles per mm for a 4 mm entrance pupil (weight = 0.02 each); MTF values ​​are 20 degrees off-axis for sagittal and tangential foci at a spatial frequency of 25 cycles per mm for a 4 mm entrance pupil that are as similar as possible (weight = 0.01). MTF was calculated using monochromatic green light at 550 nm, with the anterior haptic plane of the lens approximately 0.5 mm behind the iris in a Liou and Brennan eye model and with retinal curvature defined according to Atchinson et al. (Optical Models for Human Miotic Eyes, 2006).This optimization can be used to determine how lens parameters, such as arc height, center thickness, anterior surface curvature, posterior surface curvature, and shape factor, can be adapted (according to the lensmaker's equation) to achieve desirable sub-ranges of marking powers that are optimal for improving a patient's peripheral vision. The sub-ranges were then selected according to the region over which the observed optimization is most stable, so that the optimization effect can be predictable given the appropriate selections of structural features.

[0065] Figure 3 presents an example of intraocular lens characteristics taking into account the respective refractive indices for the media before the lens (n1), the lens material (n2), and the media after the lens (n3). With known radius curvatures (R1, R2) for the anterior lens surface and the posterior lens surface, the surface powers (i.e., AnteriorPower and PosteriorPower) of the lens can be calculated according to equations 2 and 3 given above. For AnteriorPower, nmedium corresponds to n-, while for PosteriorPower, nmedium corresponds to n2. This invention includes surface curvature values ​​in numerous diopter marking powers for the anterior and posterior surfaces of numerous different lenses with respective Petition 870250103047, dated 11 / 11 / 2025, p. 30 / 75 25 / 53 refractive indices. This invention considers an intraocular lens with a power format factor less than or equal to negative one and / or an intraocular lens with a power format factor greater than or equal to negative one. The lens body of the intraocular lens with a power format factor less than or equal to negative one may be differentially formed from the lens body of the intraocular lens with a power format factor greater than or equal to negative one. The invention may provide a lens assembly comprising at least one first lens with a power format factor less than or equal to negative one. Additionally or alternatively, the lens assembly may comprise at least one second lens with a power format factor greater than or equal to negative one.A lens with a power format factor less than or equal to negative one and / or a lens with a power format factor greater than or equal to negative one may have a refractive index (n2) between 1.40 and 1.50 and / or a refractive index (n2) between 1.50 and 1.60. Other refractive index ranges are considered. The refractive index may be between 1.45 and 1.48. The refractive index may be between 1.54 and 1.56. The refractive index may be 1.471. The refractive index may be 1.55. The respective power format factors and radius of curvature for different refractive indices coincide with the standards established for the lenses discussed above. Indeed, the differences and similarities between the power format factors for the lenses discussed above indicate patterns that are useful for predicting the effects of lens characteristics, such as, but not limited to, arc height, as discussed above.These same effects can be shown in additional tests for lenses with varying refractive index values ​​as revealed here.

[0066] This invention establishes structural factors for intraocular lenses that have shown exceptional results for foveal vision and peripheral vision after implantation according to the optimization discussed. Petition 870250103047, dated 11 / 11 / 2025, page 31 / 75 26 / 53 in the present invention. Lenses with a power format factor less than or equal to minus one

[0067] As mentioned above and as demonstrated in Figures 4 to 7 show that certain lower marking powers, for example, marking powers for a lens with a power format factor less than or equal to negative one, exhibit power format factor values ​​that are less stable in this lower marking power range. The lower marking power range can be from 7 D to 17 D. As further shown by Figures 4 to 7, similar uncertainty is seen at higher marking powers above 28 D and below 36 D for a lens with a power format factor less than or equal to negative one. This provides a basis for fine-tuning the anterior surface curvature and posterior surface curvature of each lens at each marking power.Due to the selection of central thickness, arc height, and format factor within the ranges described in this invention, the anterior surface curvature and posterior surface curvature can be adjusted to produce peripheral vision lenses with stable power response over a range of marking powers. As demonstrated by graph 400 of Figure 4, the range in which the power response is stable for an intraocular lens with a power format factor less than or equal to minus one and a refractive index between 1.40 and 1.50 is from 17 D to 23 D. With reference to graph 500 of Figure 5, for an intraocular lens with a power format factor less than or equal to minus one and a refractive index between 1.50 and 1.60, the stable range of marking powers is between 20 D and 28 D.Lenses with these marking bands have a readily predictable ability to optimize visual acuity along the axis to be as close as possible to the diffraction-limited performance limit, while correcting peripheral vision. Petition 870250103047, dated 11 / 11 / 2025, p. 32 / 75 27 / 53

[0068] One embodiment of a peripheral vision intraocular lens comprises a lens body. The lens body has a diopter labeling power between 17 D and 23 D and a refractive index value between about 1.40 and 1.50. For these labeling powers and refractive indices, the power format factor is between -1 and -2.5. The first surface may have an anterior surface curvature between -0.77 mm⁻¹ and 0.00 mm⁻¹. The second surface may have a posterior surface curvature between -0.355 mm⁻¹ and -0.130 mm⁻¹. The central thickness may be between 0.62 mm and 1.0 mm. An anterior haptic may be connected to the lens body to hold the lens in place after implantation, and the intraocular lens may exhibit an arc height between 0.34 mm and 0.65 mm.

[0069] For a lens body modality with a refractive index between approximately 1.50 and 1.60 and diopter marking powers between 20 D and 28 D, the power format factor is between -1 and -3. The first surface may have an anterior surface curvature between -0.022 mm-1 and 0.00 mm-1. The second surface may have a posterior surface curvature between -0.170 mm-1 and -0.081 mm-1. The central thickness may be between 0.45 mm and 1.0 mm. An anterior haptic may be attached to the lens body to hold the lens in place after implantation, and the intraocular lens may exhibit an arc height between 0.30 mm and 0.65 mm.

[0070] An intraocular lens comprising a lens body made according to the following sub-ranges of marking power and power format factor can be provided. The marking power sub-range can be between 18 D and 22 D for a lens with a refractive index between about 1.40 and 1.50 and between 20 D and 27 D for a lens with a refractive index between 1.50 and 1.60. With reference to the optimization function of Figures 6 and 7, the narrow bands 610 and 710 of the optimization function within these sub-ranges demonstrate that lenses made with marking powers within the sub-ranges have an even more stable format factor in this range, compared with the wider ranges. Petition 870250103047, dated 11 / 11 / 2025, page 33 / 75 28 / 53 wide discussed above. This stability means that it is easier to predict which structural features will result in lenses that are able to maximize visual acuity on the axis while minimizing off-axis astigmatism at 20 degrees of eccentricity according to the optimization MTF described in this application.

[0071] In one embodiment, the lens has a diopter marking power between 18 D and 22 D and refractive index values ​​between approximately 1.40 and 1.50. The lens has a power format factor between -1.1 and 2.0. In this case, the first surface may have an anterior surface curvature, or between -0.071 mm-1 and -0.00 mm-1. The second surface may have a posterior surface curvature between -0.355 mm-1 and -0.134 mm-1. The central thickness for the lens may be between 0.70 mm and 0.90 mm. An anterior haptic may be connected to the lens body to hold the lens in place after implantation, and the intraocular lens may exhibit an arc height between 0.40 mm and 0.60 mm.

[0072] An additional embodiment of a lens has a diopter marking power between 20 D and 27 D and a refractive index between approximately 1.50 and 1.60. In this case, the lens has a power format factor between -1.0 and -2.4. The first surface may have an anterior surface curvature between -0.022 mm-1 and -0.00 mm-1. The second surface may have a posterior surface curvature between -0.170 mm-1 and -0.084 mm-1. The central thickness may be between 0.55 mm and 0.90 mm. An anterior haptic may be attached to the lens body to hold the lens in place after implantation, and the intraocular lens may exhibit an arc height between 0.35 mm and 0.60 mm. Lenses with a power format factor greater than or equal to minus one.

[0073] As discussed above, for an intraocular lens with a marking power greater than a transition point power, the intraocular lens includes a lens body that can be formed Petition 870250103047, dated 11 / 11 / 2025, p. 34 / 75 29 / 53 differentially from the lens body for an intraocular lens with a marking power lower than a transition point power. The transition point power may be a marking power corresponding to an intraocular lens with a format factor of -1. For example, with reference to Figure 4, the transition point power may be 23 D, 24 D, or 25 D for a lens with a refractive index between 1.40 and 1.50. With reference to Figure 5, for a lens with a refractive index between 1.50 and 1.60, the transition point power may be 23 D, 25 D, or 28 D. Other transition point powers may be chosen as appropriate.

[0074] For higher marking powers for lenses with a power format factor greater than or equal to negative one, the rate of increase of power format factors in these marking power ranges diverges, but to a lesser extent than discussed previously for marking powers lower than the transition point power. With reference to Figure 4, between certain increasing marking powers, the rate of increase of power format factors in this marking power range exhibits little variation. These marking power ranges may be between 23 D and 30 D for a lens with a power format factor greater than or equal to negative one and a refractive index between 1.40 and 1.50, or between 23 D and 35 D for a lens with a power format factor greater than or equal to negative one and a refractive index between 1.50 and 1.60.Within these ranges, the anterior surface curvature and posterior surface curvature can be refined to produce readily predictable variation in the shape factor across the entire range. This stability increases the ability to predict the structural characteristics that allow lenses to correct peripheral vision while optimizing visual acuity along the axis.

[0075] One lens modality has a diopter marking power between 23 D and 30 D and refractive index values ​​between approximately Petition 870250103047, dated 11 / 11 / 2025, p. 35 / 75 30 / 53 1.40 and 1.50. The power format factor is between -0.2 and -1. For these ranges, the first surface can have an anterior surface curvature between 0 mm⁻¹ and 0.120 mm⁻¹. The second surface can have a posterior surface curvature between -0.367 mm⁻¹ and -0.130 mm⁻¹. The central thickness can be between 0.62 mm and 1.0 mm. An anterior haptic can be connected to the lens body to hold the lens in place after implantation, and the intraocular lens can exhibit an arc height between 0.34 mm and 0.65 mm.

[0076] One embodiment of a lens with a refractive index between approximately 1.50 and 1.60 has diopter marking powers between 23 D and 35 D. The power format factor is between -0.2 and -1. In this case, the first surface may have an anterior surface curvature between 0.00 mm⁻¹ and 0.082 mm⁻¹. The second surface may have a posterior surface curvature between -0.179 mm⁻¹ and -0.081 mm⁻¹. The central thickness may be between 0.45 mm and 1.0 mm. An anterior haptic may be attached to the lens body to hold the lens in place after implantation, and the intraocular lens may exhibit an arc height between 0.30 mm and 0.65 mm.

[0077] Within at least one example subrange, such as between D and 29 D for a lens with a power format factor greater than or equal to minus one with a refractive index between 1.40 and 1.50, as shown in area 620 of Figure 6, or between 25 D and 35 D for a lens with a refractive index between 1.50 and 1.60, as shown in area 720 of Figure 7, the rate of increase of the power format factors is determined so that the differences are statistically insignificant and the power format factor appears to exhibit even greater stability. These subranges can be selected in order to optimize the structural characteristics of the intraocular lens to result in minimized off-axis astigmatism at 20 degrees of eccentricity and maximized on-axis visual acuity, thus improving vision. Petition 870250103047, dated 11 / 11 / 2025, page 36 / 75 31 / 53 peripheral. An intraocular lens comprising a lens body, made in accordance with the following sub-ranges of marking power and power format factor, can be provided in order to maximize visual acuity on the axis while minimizing off-axis astigmatism at 20 degrees of eccentricity according to the optimization disclosed herein.

[0078] An additional embodiment of a lens has a diopter marking power between 24 D and 29 D, a refractive index between approximately 1.40 and 1.50, and a power format factor between -0.3 and -0.8. In this case, the first surface may have an anterior surface curvature between 0 mm⁻¹ and 0.12 mm⁻¹. The second surface may have a posterior surface curvature between 0.36 mm⁻¹ and 0.13 mm⁻¹. The central thickness for the lens may be between 0.70 mm and 0.90 mm. An anterior haptic may be attached to the lens body to hold the lens in place after implantation, and the intraocular lens may exhibit an arc height between 0.40 mm and 0.60 mm.

[0079] A lens modality with a diopter marking power between 25 D and 35 D and refractive index values ​​between approximately 1.50 and 1.60 has a power format factor between -0.7 and -0.95. In this case, the first surface may have an anterior surface curvature between 0.01 mm-1 and 0.082 mm-1. The second surface may have a posterior surface curvature between -0.179 mm-1 and -0.081 mm-1. The central thickness for the lens may be between 0.55 mm and 0.90 mm. An anterior haptic may be connected to the lens body to hold the lens in place after implantation, and the intraocular lens may exhibit an arc height between 0.35 mm and 0.60 mm. lens set

[0080] A lens set may be supplied, wherein the lens set comprises at least one lens with a power format factor less than or equal to minus one as defined above and / or at least one lens with a power format factor Petition 870250103047, dated 11 / 11 / 2025, p. 37 / 75 32 / 53 greater than or equal to minus one as defined above. The lens set may comprise a series of lenses. The diopter marking power of each lens in the lens series may vary by at least 0.25 D compared to the other lenses in the lens series. For example, the lens series may comprise 5 lenses with diopter marking powers of 17.5 D, 17.75 D, 18 D, 18.25 D, 18.5 D. The diopter marking power of each lens in the lens series may vary by 0.5 D, 1 D, 2 D, 3 D, 4 D, or 5 D compared to the other lenses in the lens series. The lenses in the lens set may have a marking power below a transition point power or a marking power above a transition point power.The intraocular lens body with a marking power above the transition point power can be differentially shaped from the intraocular lens body with a marking power below the transition point power. The transition point power is a marking power that corresponds to an intraocular lens with a format factor of -1. For example, with reference to Figure 4, the transition point power can be 23 D, 24 D, or 25 D for a lens with a refractive index between 1.40 and 1.50. With reference to Figure 5, for a lens with a refractive index between 1.50 and 1.60, the transition point power can be 23 D, 25 D, or 28 D. Other transition point powers can be chosen as appropriate.

[0081] The provision of a lens set allows for the correction of peripheral vision for prescriptions requiring a dioptric power lower than a transition point power, as well as the correction of peripheral vision for prescriptions with a dioptric power higher than a transition point power. The embodiments of the lens set of the invention therefore allow for the correction of peripheral vision across the entire range of possible prescriptions. Advantageously, the set can provide a range of lenses that can be selected by a user for Petition 870250103047, dated 11 / 11 / 2025, p. 38 / 75 33 / 53 to adapt the selected lenses to the patient's dioptric power requirements.

[0082] According to areas 610 and 620 in Figure 6, an embodiment of a lens set with a refractive index between 1.40 and 1.50 comprises at least one first lens with a diopter marking power between 17 diopters and 23 diopters with a power format factor that is less than or equal to -1.0 and greater than or equal to -2.5, and at least one second lens with a diopter marking power between 23 diopters and 30 diopters and with a power format factor that is less than or equal to -0.2 and greater than or equal to -1. Within these ranges, the anterior surface curvature and the posterior surface curvature can be refined to produce readily predictable variation in the format factor throughout the range. This stability increases the ease with which the lenses are able to correct peripheral vision while optimizing visual acuity on the axis.

[0083] For at least one first lens, the first surface may have an anterior surface curvature between -0.77 mm-1 and 0.00 mm-1. The second surface may have a posterior surface curvature between 0.355 mm-1 and -0.130 mm-1. The central thickness may be between 0.62 mm and 1.0 mm. An anterior haptic may be connected to the lens body to hold the lens in place after implantation, and the intraocular lens may exhibit an arc height between 0.34 mm and 0.65 mm.

[0084] For at least one second lens in the lens assembly, the first surface may have an anterior surface curvature between 0 mm⁻¹ and 0.120 mm⁻¹. The second surface may have a posterior surface curvature between -0.367 mm⁻¹ and -0.130 mm⁻¹. The center thickness may be between 0.62 mm and 1.0 mm. An anterior haptic may be connected to the lens body to hold the lens in place after implantation, and the intraocular lens may exhibit an arc height between 0.34 mm and 0.65 mm.

[0085] According to areas 710 and 720 in Figure 7, a second Petition 870250103047, dated 11 / 11 / 2025, page 39 / 75 The 34 / 53 modality of a lens set comprises lenses with a refractive index between 1.50 and 1.60. The lens set comprises at least one first lens with a diopter marking power between 20 D and 28 D with a power format factor between -1 and -3 and at least one second lens with a diopter marking power between 23 D and 35 D and with a power format factor that is between 0.5 and -1. Within these ranges, the anterior surface curvature and the posterior surface curvature can be refined to produce readily predictable variation in the format factor throughout the range. This stability allows for greater predictability in producing lenses capable of correcting peripheral vision while simultaneously optimizing visual acuity on the axis.

[0086] For at least one first lens in the second embodiment of the lens set, the first surface may have an anterior surface curvature between -0.022 mm-1 and 0.00 mm-1. The second surface may have a posterior surface curvature between -0.170 mm-1 and -0.081 mm-1. The center thickness may be between 0.45 mm and 1.0 mm. An anterior haptic may be connected to the lens body to hold the lens in place after implantation, and the intraocular lens may exhibit an arc height between 0.30 mm and 0.65 mm.

[0100] A method for designing an array of intraocular lenses to improve peripheral vision can be provided. The method may comprise providing an intraocular lens with an optical power that reduces optical errors in an image produced at a peripheral retinal location of a patient's eye positioned at a distance from the fovea. An intraocular lens can be provided for each increment of 0.25 D for the range of 17 D to 35 D. As the lens marking power increases from 17 D to 35 D, the power format factor increases from 3.0 to -0.2. For marking powers corresponding to a factor Petition 870250103047, dated 11 / 11 / 2025, p. 44 / 75 For formats below the transition point power, the intraocular lens comprises a first lens body with a format factor less than or equal to -1 according to the modalities discussed above.

Each intraocular lens may have a defocus parameter less than 1.8 D.

[0101] Other methods for designing a lens assembly are provided for within the scope of this invention.

[0102] An intraocular lens according to this invention may also utilize complex surfaces, such as Zernike surfaces and toroidal surfaces, in addition to other variable and non-uniform surface structures for the anterior and posterior surfaces of a lens body. In a non-limiting embodiment of an intraocular lens, the first surface has an anterior radius and exhibits an anterior power; a second surface has a posterior radius and exhibits a posterior power.

The first power value and the second power value may have equal or different values ​​for a respective diopter marking power. At least one of the first or second surfaces has a refractive profile. Complex surfaces, therefore, may use anterior and posterior radii values. Petition 870250103047, dated 11 / 11 / 2025, page 45 / 75 40 / 53 posterior variable and first variable power values. The complex surface may also include a validated power format factor having only the second power factor calculated with the anterior and posterior power. In the modalities, at least one of the first or second surfaces includes a toric surface. The power format factor for the intraocular lens has a toric surface with an average of power meridians calculated for distinct portions of the intraocular lens surfaces. In additional modalities, additional power may be added to the diopter labeling power, with the power format factor remaining equal to the second power value calculated with a baseline anterior power and a baseline posterior power.

[0103] In another embodiment of an intraocular lens according to this invention, the intraocular lens has a first surface with an anterior radius and exhibiting an anterior power and a second surface with a posterior radius and exhibiting a posterior power. Optionally, at least one of the first surface or the second surface is a complex surface with multiple curvatures through the surface. Like other lenses described above, the intraocular lens exhibits a power format factor, relative to a constant plano-convex power format factor and corresponding to a marking power measured in diopters. The power format factor may have a first power value, calculated with the anterior radius and the posterior radius, and a second power value, calculated with the anterior power and the posterior power.The first power value and the second power value may have different values ​​for a respective diopter marking power. In non-limiting lenses of this invention, the complex surface may have variable anterior and posterior radius values ​​and variable first power values. The complex surface may additionally include a validated power format factor calculated with only the second. Petition 870250103047, dated 11 / 11 / 2025, page 46 / 75 41 / 53 power factor, which, in turn, is calculated with the overall anterior surface power and the overall posterior surface power, where the overall powers represent the different radii of curvature. In some embodiments, at least one of the first or second surfaces includes a toric surface (i.e., exhibiting a torus or toroidal shape across at least a portion of the surface). The power shape factor for the intraocular lens having a toric surface may be an average of power meridians calculated for distinct portions of the intraocular lens. In some cases, the intraocular lenses of this invention have additional power added to the marking power, wherein the power shape factor remains equal to the second power value calculated with a baseline anterior power and a baseline posterior power.

[0104] In some situations, this invention describes relationships between optical components in terms of position or in terms of operational parameters being comparable to each other. These descriptions are not limiting to the invention, but are presented for illustrative purposes only. In fact, when this invention uses numerical values ​​for dimensions or ranges, all numerical values ​​are understood to be about or approximately equal, and these phrases should be given the broadest meaning in the context of the technology. In some embodiments, the magnitudes of certain optical parameters may be about a certain value or approximately equal if the magnitudes differ from each other by an amount that is within a selected range of 0 to 5 percent of the larger value. The ranges in this invention include the endpoints, unless otherwise specified or unless the context of the range dictates otherwise.

Measurements may be taken by manifest refraction, autorefraction, tomography, or a combination of these or other measurement methods. The optical aberrations of the patient's eye may also be determined.

[0106] A determination of the patient's visual range can also be made. For example, the patient's ability to focus on near objects (presbyopia) can be measured and determined. An additional power range for the ophthalmic lens can be determined.

[0107] The patient's eye measurements can be put into an ophthalmic lens prescription, which includes features of at least one optical element that is intended to address the optical aberrations of the patient's eye, as well as features that address the visual range for the patient (e.g., an amount of additional power and the number of foci to be provided by the optical element).

[0108] The ophthalmic lens prescription can be used to manufacture an optical element for the ophthalmic lens. A refractive profile of the optical element can be determined based on the ophthalmic lens prescription to correct the optical aberrations of the patient's eye. Such a refractive profile can be applied to the optical element either on a surface including the diffraction profile or on an opposite optical surface. The diffraction profile can also be determined to provide the desired distribution of additional power to the optical element.

[0109] The determination of one or more refractive or diffractive profiles and the fabrication of the optical element may be performed remotely from the optometrist, ophthalmologist or other medical professional or Petition 870250103047, dated 11 / 11 / 2025, p. 48 / 75 43 / 53 optical that performed the measurements of a patient's eye or can be performed in the same clinical facility as such individual. If performed remotely, the manufactured optical element can be delivered to an optometrist, ophthalmologist, or other medical or optical professional to be provided to a patient. For an intraocular lens, the manufactured optical element can be provided for implantation in a patient's eye. The manufactured optical element can be made according to the embodiments of this invention.

[0110] The manufactured optical element may be a custom-made optical element manufactured specifically for the patient's eye, or it may be manufactured in a manufacturing set and then selected by an optometrist, ophthalmologist, or other medical or optical professional for delivery to a patient, which may include implantation in the patient's eye.
